问题描述

是否可以检测屏幕旋转?我的意思是 - 仅轮换，这与活动初始化与另一个活动有明显区别?

is it possible to detect screen rotation? I mean - rotation only, which is clearly distinguishable from activity initialization from another activity?

onXxx 方法似乎对此没有用，我尝试从 starting Intent 添加/删除 flag (删除似乎没有反映，在旋转标志在那里)，并尝试为清单中的活动添加 android:configChanges="orientation" ，但是 onConfigurationChanged 方法似乎每秒钟旋转一次...有线.

The onXxx methods seem not to be useful for this, I have tried adding/removing a flag from the starting Intent (the removing seems not to be reflected, on rotate the flag is there), and have tried adding android:configChanges="orientation" for the activity in the manifest, however the onConfigurationChanged method seems to be called every second rotation... wired.

我想我遗漏了一些东西......但在其他相关线程中没有找到明确的解决方案.

I guess I am missing something... but haven't found clear solution in the other related threads.

有什么想法吗?

推荐答案

清单:

<activity android:name=".MyActivity" android:configChanges="screenSize|orientation|screenLayout|navigation"/>

活动:

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    Log.d("tag", "config changed");
    super.onConfigurationChanged(newConfig);

    int orientation = newConfig.orientation;
    if (orientation == Configuration.ORIENTATION_PORTRAIT)
        Log.d("tag", "Portrait");
    else if (orientation == Configuration.ORIENTATION_LANDSCAPE)
        Log.d("tag", "Landscape");
    else
        Log.w("tag", "other: " + orientation);

    ....
}
